[[http://www.uniprot.org/uniprot/FIBA_HUMAN FIBA_HUMAN]] Defects in FGA are a cause of congenital afibrinogenemia (CAFBN) [MIM:[http://omim.org/entry/202400 202400]]. This is a rare autosomal recessive disorder characterized by bleeding that varies from mild to severe and by complete absence or extremely low levels of plasma and platelet fibrinogen. Note=The majority of cases of afibrinogenemia are due to truncating mutations. Variations in position Arg-35 (the site of cleavage of fibrinopeptide a by thrombin) leads to alpha-dysfibrinogenemias. Defects in FGA are a cause of amyloidosis type 8 (AMYL8) [MIM:[http://omim.org/entry/105200 105200]]; also known as systemic non-neuropathic amyloidosis or Ostertag-type amyloidosis. AMYL8 is a hereditary generalized amyloidosis due to deposition of apolipoprotein A1, fibrinogen and lysozyme amyloids. Viscera are particularly affected. There is no involvement of the nervous system. Clinical features include renal amyloidosis resulting in nephrotic syndrome, arterial hypertension, hepatosplenomegaly, cholestasis, petechial skin rash.<ref>PMID:8097946</ref> | |||
==Function== | |||
[[http://www.uniprot.org/uniprot/FIBA_HUMAN FIBA_HUMAN]] Fibrinogen has a double function: yielding monomers that polymerize into fibrin and acting as a cofactor in platelet aggregation. [[http://www.uniprot.org/uniprot/THRB_BOVIN THRB_BOVIN]] Thrombin, which cleaves bonds after Arg and Lys, converts fibrinogen to fibrin and activates factors V, VII, VIII, XIII, and, in complex with thrombomodulin, protein C. Functions in blood homeostasis, inflammation and wound healing (By similarity). | |||
